e LQOSE-LEAF BINDER. i i

Application filed December'S, 1926. Serial No. 1333/180 My invention relates to loose-leaf binders andmore particularly to that type thereo which is shown in my Patent No. 1,4( S9,573,

'of October 2, 1923, and has for its ob ect to provide avnovel and improved constructon, whereby the insertion of the elements carrying the material to be bound and their renioval :from the binder are facilitated and simplified. Other more specific object-s will appear from the description hereinatter and the features of novelty will be pointed out in the claims.

In the accompanying drawings, which illustrate an example ot' myinvention withont defining its limits', Fig; l is a perspect ve View of my invention applied to a cover with the latter in its open position and with removable bindin strips in place therein; Fig. 2 is a similar view with the binding strips removed and the binder adjusted to facilitate removal or replacement of sai d strips; Fig. 3 is a perspective ,Viewof a binding strip adapted for use With the binderyFig. 4; is a perspectve view of a sheet, recessed in a' manner *to fit the binder; Fig. 5 is a section on the line 5-5 of Fig. 1, on an enlarged scale'F ig. 6 is a planview onan enlarged scale of the aforesaid invention; Fgs. '7, '8 and 9 `are detail perspective views illustrating separately several units which constitute parts of the ,bindem Fig.-10 is a detail ,section on the line 10-10 of Fig. 6 showingthe end unit of the binder in its open position; Fig. 11 is a cross-section showing another form' of the v binder.

The invention in all of its forms consists essentially ot two recessed retaining` members located in opposed spaced relation to each other with the recesses of said members facng each other, in combination with binding strips arranged for connection with the material to be'bound and having their oppo-` site ends located in the recessed retaining members so as tobe normally held thereby to removably fix the material in the binder; in cases where thephysca'l characterstes of 'the material are such as to permitit the use of the binding strips maybe avoided by combining the material .to be bound directly V with the retaining members; if the material to be bound comprises sheets .this may be accomplished by properly recessing the latter. In any case the arrangement is such that the holding relation which normally` exists between the ends of the binding strips and the retaining members, or between the bound 'sheets or their equivalent, may be relieved at will at least with respect to one of said retainmg members and the cooperating ends 'of the binding strips or adjacent portions of said sheets or their equivalent to thereby per mit the ready removal otthe binding strips, sheets, etc., from the bindet without requiring said strips, sheets or their equivalent to be flexed. i

This result may be accomplished, for instance, by providing one recessed retaining member 10 consisting of a substantially recta ngular receptacle monnted upon a carrying member ll which, as shown, may comprise an extension of the rear wall of said recessed member; the member 10 is' open only in a direction toward the opposed recessed member 12 and may be otherwise closed. The opposed retaining member 12, instead ot being` a fixed receptacle includes a slidable lockng 'section 13 which is slidably mounted upon' the member 12, the latter also having one of.

itswalls extended to constitute a carrying member l l. The member 12 is without top or bottom walls but includes an outer end wall as shown in Fig. 9, while the slidable 'section -13 includes a bottom wall 15 and a relatively reduced top wall 16. In theoperative position ot the parts the bottom wall 15 registers with the member 12 and constitutes the bottom thereof and the rednced top wall 16 occupies a position in which it partly closes the top ot the member 12. A si'itable stop 17 is provided onthe.slidablesection 13 :for engagem'ent with the outer end wall of the member 12 to arrest the movement of the section 13. toward ts'opcrative position and a corre- ,sponding stop 18 depends from the-top wall ol' engagement With said'outer end wall of the member 19 to arrest the movement of said section 13 toward its inoperative position. i V e i In the illustrated arrangement, the carrying members 11 and 14 are fixed upona supporting member 19 'for nstance by means of rivets 20 or the like; ii' desired tongues 10 maybe stainped from the recessed members 10 and 12 for engagement with the ends of the supporting member 19 as shown in Fig; 6. The Construction 'is such that in the normal position of the parts, the distance between the 'inner 'end edges ?of the bottom of the reeessed member and the corresponding edge of the bottom of the slidable section 13 of the other recessed member 12, is less than the distance between 'the opposite ends of the binding strips 21 or the outer edges of the leaves 22 or the like, so thatsaid binding strips or 'said leaves are locked in said recessed members, as is clearly shown in v whereby the inner end edge of the top wall oi' said section 13 is shifted to a position beyond the contiguous ends of the binding strips 21 or beyond the edges of the leaves 22 and thus permits either 'the strips 21 or the leaves 22 'to be easily lifted out of this particular reeessed member and then withdrawn from the other.

without interference. The device may be restored to its operative condition by simply returning the'slidabie section 13 to its initial position on the member 12. The irictional engagement between'the section 13 and the member 12 is sufiicient to maintain the section 13 in its inner operative position against unintentional movement in an outward direction and also in its outer inoperative position.

If desired an intermediate member 25 may be secured upon the supporting member 19; the member 25 as shown n Fg; 2 IS provided with lugs 26 which project inw'ardly therefrem so as to eXtend over the binding members at intermediate points thereof to maintain said binding membersin their intended positions. Instead oil? being independent elements fixed upon the supporting member 19, the latter and the retaniing members 10 and 13, with the intermediate member 25, if it forms part of the device, may be constructed in the form of an integral unit. The device so far described is preferably combined with a suitable cover in which case the supporting member 19 is Secured to the back of the cover in any convenient manner. The cover itself may be of any conventional form and ofsuitable dimensions and comprises two sections 27 adapted to beifolded over each other in the usual way.

Instead of e onstructing the device as illustrated in Figs. 1 to 10 inclusive and as so far 'described both retaining members 10 and 12 may comprise units located in fixed relation to each other so as to be incapable of any adjustment either toward or awayfrom each other, said retaining members being arranged to receive and hold the opposite ends of the binding strips or the leaves in the same manner as hereinbefore set for-th. In this case, however, either one or both o' the retaining members 10 may be upwardly open and' provided as shown in Fig. 11 with a hinged cover 28 which in its normal position constitutes the top wall o' the particular retaining member of which it :forms a part to establish the holding relation between said retaining member and the cooperatmg ends of the binchng strps 21 or parts ofthe leaves 22.

The device in all of its forms is of simple in which the material is removably maintained in a condition of easy aceessibility; the arrangement provides for the removal of the bound material from and its placement in position in. the binder with a minimum of effort and without the necessityior any particconstruction and provides an eiicient binder ular skill on the part of the person using the binder. i

It will of course be understood that the specific means whereby the holding 'elation between the binder and the material boun'd therein is developed or relieved at will, which is exemplified in the illustrated examples by the slidable section 13'and the hinged cover 28, may comprise a variety of difierent devices.

Various changes in the specificform shown and described may be made in the scope of the claims without departing` from the spirit'of my invention I claim:

1. A loose-leaf binder comprising opposed reoessed retaining members 'opening toward in spaced relation, binding strips.

each other adapted for connection with the material to be bound, and having their opposite ends projecting into said recessed and held thereby, and means 'con'prising'a movable part of one of said retaining members and adjustable to'a position in which the holding relation between said' one retaining 'memberand the 'cooperating ends of said binding strps may be relieved at will to thereby free the latter and permit said strips to be removed from the binder.

2. A loose-leaf binder eomprising opposed recessed retaining members located in spaced relation and opening toward each other for e receiving the material to be bound, and .means slidable on one of said retaining members'to a positlon m-whch theholding relation between said one retamng member and the cocorresponding to* retaining members The cover 28is capav ble of bem swung rela tlvely to saidretamng member to the open 'position shown in Flg. 11. I

portions withdrawn from the other mem- Operating portions of said material is reiieved at will to thereby free the latter and permt the material to be removed from the binder. g

3. A loose-ieaf binder comprising a pair of opposed recessed retaining members opening toward each other in spaced relation for receving the material to be bound, and a lockng section slidably mounted on one of said retaining members and slidable toward and away from the other retaining member to an operative position, and to an inoperative position in which the holding relation between said one retaining member and the cooperating portions of said bound material is `relieved at will to 'thereby free the latter and permit said material to be removed from the binder. i

4. A loose-leaf binder comprising a pair of opposed recessed retaining members opening toward each other in spaced relation, binding strips adapted for connection with the material to be bound and having their opposite ends projectng into the recessed retaining members' and normally'held thereby, a supporting member on which said retaining members are mounted, and a slidable looking section on one of said retainng members movable toward and away from the other retaining member to an operative position, and to an inoperative position `in which the holding relation between said one retaining member 'and the cooperating ends of said binding strips is relieved tothereby free the latter and permit said bnding strips from the binder. v i

to be removed r 5. Aloose-leaf binder comprising opposed i reeessed' retaining members opening toward each other and fixed in spaced relation to, each other and arranged to receive the material to be bound, one of said retaining members being upwardly open, and a device movably mounted on said upwardly open retaining member and forming the upper wall thereof in its normal position and movable to an insaid material to thereby free the latter and permit said material to be removed from the binder, means for arresting the outward movement 'of said movable section and means for arresting the inward movement thei-coi'. In testimony whereof I have hereunto set my hand. y
